AUTOMATIC UNCOUPLER.

SPECIFICATION forming part of Letters Patent No; 286,920, dated October 16, 18821.

' nppiicationnlea August 14, 1853. No modem .To a/ZZ whom it may concern: Y

Beit known that I, WILsON R. FUNK, a citizen of the United States, residing at Cleves, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Automatic Uncouplers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had` to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. A

The object of my invention is to provide an automatic uncoupler for coal or other dumpcars, attached to the ropes or cables of elevators or incline planes.

In the accompanying drawings, Figure 1 represents a side view of the Vautomatic uncoupler, exposing the interior, with the lock or trigger down, and coupled to the cable-link of a coal-elevator. Fig. 2 is a side view Of the same exterior view, with the lock or trigger raised and the cable-link uncoupled. Fig. 3 is a front view of Fig. 2 without the linkand cable. Q

Similar letters of reference represent corresponding parts.

In the drawings, A is an iron or metal detent, which swings upona rivet, b, insideof the body C. At the lower part of the detent is a mouth, d, through which passes a link, E, attached to a cable, F. The lower lip, G, holds the link in the mouth d.

H is a lock or trigger swung on a pivot, e, within the body C, resting upon a spiral spring, J, which holds the detent A firmly in its place by means of the notch X. The lock or trigger H is operated by a two-handled lever, K K, the cam f of which rests upon the lock Or trigger just above ,the spring J.

dump-car by means of bolts through the open,

ings in the plates at M and N N. The cable F, which is attached to a stationary steam-engine or other hoisting-power, draws the dumpcar up the elevator or incline plane to the level at the top. To the level floor O of the elevator are attached two diagonal blocks, P l

P, upon which the handles of the lever K K strike and are elevated in passing over. This raising of the lever K K upon the blocks P P presses down the spiral spring J, raises the lock or trigger H out of the notch X, permits the detent A to turn on its rivet b, and allows the link and cable E `of the elevator tobe pulled out ofthe mouth d by the hoisting-power alone, thus uncoupling the dump'car from the hoisting-power without the employment of a hand' in a dangerous position forthat purpose.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The detent A,`swung within an iron or metal body, C, with a lip, G, in combination `with the lock or trigger H, springpJ, and lever K K, as and for the purpose set forth.

2. The lock or 'trigger H, in combination with the detent A, spring J, levers K K, and diagonal blocks P P, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILSON ROBERT FUNK.
